Thus, providing ubiquitous connections to/from a mobile device is crucial for various future ZigBee applications. Knowledge of how nodal mobility affects the ZigBee routing protocol is import

Thus far, researchers have been unable to analyze and evaluate the impact of mobile applications via extensive simulations. In this paper, our contribution is threefold. First,

Second, we analyze the adequacy of current provisions for dealing with different mobility cases. Third, we provide a comprehensive set of simulat

The ZigBee standard3, which is designed to interconnect simple devices, represents the latest attempt to

Additionally, there are many ZigBee applications for home-appliance networks, as well as in the areas of home healthcare, medica

13、l monitoring, consumer electronics,and environmental sensors. ZigBee is a network and application layer specification developed by a multi-vendor consortium called the ZigBee Alliance. Backed by more than 150 member companies, the ZigBee standard was ratified in late 2004, and released for public non-commercial use in June 2005. Although various ZigBee compliant product prototypes and application scenarios have been developed or defined by the industry, the performance and support facilities of ZigBee networks have not been thoroughly evaluated.
